Soil Removal in Scotland: How Much Soil You Have, What It Costs and How Quickly It Can Go

A garden dig-out or driveway excavation can produce more soil than it first appears. The useful questions are how much space the spoil will take up, how heavy it is when wet, and whether it will fit within a grab lorry’s safe load.

You do not need an exact weight before asking for a quote. A few measurements, the soil type and details about access give us a practical starting point.

Measure the excavation

For a simple rectangular area, estimate the soil in cubic metres:

Length × width × depth = volume in cubic metres

Measure the depth you plan to excavate, not just the surface area. Convert centimetres to metres first: 30 cm is 0.3 m.

For example, a 20 m² area dug to 30 cm gives:

20 × 0.3 = 6 m³ before excavation

Once soil is dug out, it becomes loose and may take up more room than it did in the ground. For an early estimate, allow around 10–20% extra for loosened soil and uneven excavation. Roots, stones and changes in depth can also affect the final quantity.

Turn volume into tonnes

Volume helps you picture the pile. Weight matters when arranging soil removal, because a lorry’s capacity is limited by both the amount of space available and the safe weight it can carry.

As a broad planning guide, freshly dug ordinary soil may weigh around 1.4–1.7 tonnes per cubic metre. Wet, clay-heavy or saturated soil can weigh more. These are estimates, not a final load calculation.

A rough way to plan is:

Loose soil volume × estimated tonnes per cubic metre = estimated weight

A cubic metre of soil is often compared with roughly two standard bulk bags by volume, but bag sizes and fill levels vary. A wheelbarrow can also help you picture a small amount: a barrow with an 80-litre capacity holds 0.08 m³ when level-full. In practice, the number of trips depends on how much you can safely carry each time.

These comparisons help with planning. They do not replace checking the quantity and weight for your job.

How much fits in a grab lorry?

A full grab lorry load can carry up to 16 tonnes. That is a maximum, not a promise that every load will reach 16 tonnes. Heavy, wet soil can reach the safe weight limit before the lorry body is full. Soil that is lighter or more mixed may load differently.

The grab crane does the loading, so you do not need to hand-load a skip. The excavated soil does need to be in a suitable place for the crane to reach, and the driver must be able to work safely.

Vehicle access matters too. Our lorry is approximately 9.5 metres long, 2.6 metres wide and 3.7 metres high when empty. It can be up to 4.9 metres high when loaded. Tell us about narrow entrances, parked cars, slopes, soft ground, overhead cables and low branches so we can check whether the site is suitable.

Typical project estimates

The examples below are planning guides. Soil type, moisture, stones, excavation depth and loose volume can change the number of loads.

Garden dig-out: A 20 m² garden area excavated to 30 cm produces about 6 m³ before excavation. Allowing for loosened material gives approximately 6.6–7.2 m³. At around 1.4–1.7 tonnes per cubic metre, that is roughly 9–12 tonnes. It may fit in one load, subject to the actual weight and safe loading.

Driveway excavation: A 30 m² driveway area excavated to 30 cm produces about 9 m³ before excavation. Allowing for loose soil gives approximately 9.9–10.8 m³. That could be around 14–18 tonnes at the same broad planning range. One load may not be enough, particularly if the soil is wet or clay-heavy.

A clearer estimate comes from the dimensions and the soil condition, rather than guessing from the size of the pile.

What affects the cost?

Grab hire prices start at £220 + VAT for a typical load. The price can only be higher than this starting point, never lower. The final quote depends on factors such as location, access and disposal requirements. The estimate also needs to reflect the expected quantity and whether one load is likely to be sufficient.

You can get free estimates in seconds through our quote form. Include your postcode, what the soil is like, your estimated quantity and any access details. Quotes are usually returned within one hour during business hours.

How quickly can soil be collected?

Same-day or next-day soil collection may be available, subject to access and scheduling. Tell us when the excavation will be ready and whether the soil is already in a pile. We will check the route, site conditions and available timing before confirming an arrangement.

A quote request is an enquiry, not a confirmed booking. We will confirm the service, price and timing with you before the work is agreed.

We collect suitable excavated soil as part of our grab hire service. Green waste, timber, plasterboard and general rubbish are not part of standard soil collection. Asbestos and hazardous waste are never accepted. Keep other materials separate and tell us what the soil contains.

Bring materials in as soil goes out

If your project also needs new material, we may be able to coordinate delivery and soil collection on the same agreed visit. For example, we can deliver Type 1 or topsoil and remove excavated soil in one trip, subject to quantities, capacity, access and scheduling.

The minimum aggregate delivery is 5 tonnes. Tell us the material and quantity you need, alongside your soil estimate, so we can check whether a combined visit is practical. See the combined aggregate delivery and soil collection service.

What to send for a useful estimate

To help us work out the right option, include:

• Your postcode and preferred collection date.

• The length, width and approximate depth of the excavation.

• Whether the soil is dry, damp, wet or mainly clay.

• Where the spoil will be placed and how the lorry can reach it.

• Any new aggregate you need delivered.

We cover Glasgow, Ayrshire, Lanarkshire, Falkirk and West Lothian. Send your details through the quote form, and we will check the quantity, access and timing with you.

FAQs

Does wet soil need more than one grab lorry load?

Possibly. Wet or clay-heavy soil weighs more, so the safe weight limit may be reached before the lorry body is full. Share what you know about the soil when you request an estimate.

Is 16 tonnes a guaranteed load?

No. Up to 16 tonnes is the maximum for a full load, not a guaranteed amount for every job. The actual safe capacity depends on the material, its weight and the vehicle’s limits.

Can you collect soil from a back garden?

Often, if the grab crane can reach the prepared soil from a safe lorry position. Access, reach and working conditions need to be checked. Photos and measurements can help us assess the site.

Can you take soil with green waste or general rubbish?

No. Green waste, timber, plasterboard and general rubbish are not part of standard soil collection. Asbestos and hazardous waste are never accepted. Keep materials separate and ask us if you are unsure what is in the pile.

Can you deliver aggregate and collect soil together?

Yes, where suitable and agreed in advance. The minimum aggregate delivery is 5 tonnes, and the combined visit depends on load capacity, access and scheduling. We will confirm the details before booking.
